This invention relates to tire rim tool, adapted to expand and contract the split rim oft a motor vehicle tire, the tool including n turnlnichle and rim-engaging means carried by `the hmgitudinally moval'le members of ,turnbuclile "this invention is embodied in the iinprovernents hereinafter described and claimed,

@t the n eeompanying drawings forming' a part of this speciiieationff- .Figure l is a side view of rim tool embodying 4the invention, lool ing toward one side of the tool, and showing it adapted to contract a rim.

Figure 2 is a side `View, looking` toward anotherv side, the central member ot the turnbuelrle being shoe/'n p; tly in section.

4.llingure 3 is a View similar to a portion oft Figure 2, showing the tool adapted to expone the rim.

Figures l and 5 are perspective Views, showing respectively, one of the heads and one of the hoolrs shown by the preceding iigures. 4

The saine reference chai-"eters indicate the same parte in all ot the ligeros.

The turnlmekle includes an internally threaded rotatable central member l2, prererably provided at its midlength with an eK- ternally hexagonal enlargement 13, adapted to be engaged by a Wrench. This portion of?, the member may be provided with radial holes lei, in Whieh a screw-driver or other elongated article may be inserted, to provide a lever whereby the member may be rotated.

The externally threaded end members 15 of the tnrnbuckle are provided at their outer ls i "*h heads which include hubs l, iii? as by pins 17, to the members lo, and ears le, proj eeting in opposite directions 'from the hubs, the ea beingWpreternbly slotted, shown by ligure 4l, and overhanging the members i5. Connected by pivots 19 with the outer ends of the ears 1.8, are hooks in elnding elongated shank portions 20, and hooked outer end portions 2l, projecting inward from the shank portions, said hooks being adapted to be projected outward lengthwise of the tool as shown by Figures l and E2, and formed to engage the flanges 22 of a'split rim 23, and exert contracting pressure thereon, when the turnbuclde is being contracted.

wardly facing seats, adapted to bear,

shown by Figure E, on the inner surface of the rim 23, and exert expanding pressure thereon, the bearing of the seats on the rim preventing rotation ol the members l5 with the'- member l2. The seats are preferably dished or recessed, as shown by Figures 3 and 4l, so that the heads are free from liability to slip crosswise of the rim.

The hooks are adapted to be shifted so that they may be swung or retracted inward 'from the heads, as shown by Figure 3, thus learing the seats 'formed by the outer faces ol2 the heads, unobstructed. To enable the springs to eoniine the hooks inwardly pro jected and in out of the Way positions, l provide the hooks With laterally projieeting studs 27, with the outer ends oli which the springs 25 are connected. The springs are oll'set from the heads by the stnes. as indicated by Figure l, so that when the hooks are shifted or swung inward, the springs are shi tted with the hooks, as indicated by Figsure 3, and are adapted to confine the hooks in their retracted positions. This eonlinement of the hooks ensiues coinpaetness when the tool is not in use, and permits the storage of the tool in a tool-box rv'ithoutliability ol entangling the books with other tools in the bois.

I Claim:

l. A tire rim tool comprising a turn` buckle including an internally threaded rotatable central member, and externally threaded end members movable longitudinally in opposite directions by the rotation. ot the central member; heads lined to the outer ends of the end members and overhanging the end and central members at opposite ends of the tool hooks pivoted in pairs to opposite outer portions of the heads,

,Y and adopted to be projected outward length- Qthe pivots engage the inner t., l

ef the feel en elses@ the flesse Of split rim to exert contracting pressure on the rim when the turnbucltle is being contracted, the heads 'forming outwardly facing seat-s adapted tobear onthe inner surface of the rim to prevent rotation ot the end members with the central member and-exert expanding pressure on the rim when the turnbuclde is being elongated, the hooks beine; shittable on their pivots so that they are adapted to be retracted under the heads to expose said seats, and provided with laterally projecting studs between their pivoted and swinging ends; and contractile springs connecting,` the studs of each pair ot hooks andv offset by the studs from the heads, so that the springs are shittable with the hooks and are adapted to draw the Vbool-:s inward against the rim flanges when the hooks are projected, and to draw the hooks inward nnder the heads when the hooks arefretracted4 so that the retracted hooks are confined 'in out of the way positions.

2. A tire rim tool comprieing,` a turnbuckleA including an internally threaded rotatable central member, and erternall)T threaded end members movable longitudinally in opposite directions by the rot` tion ot' the central member; heads fixed te the outer ends .of the endinembers and ineludine; hubs and arms projecting from opposite sides ot'. the hubs and overhanging; the end and central members at opposite ends of the tool; hooks pivoted in pairs to the outer ends ot the arms and adapted to be projected outward lengthwise ot the tool and engage the ianges ot a split rim to exert contract-ine pressure on the rim when the tarnbnelrle is beine; contracted, the outer ends ot the head hubs and the outer sides ot the head arms forming` outwardlxY taeine .Gemsr adapted to bear on the inner surface ot the rim to prevent rotation of the eud members with the central member and exert expancling' presvre onthe rim when the turnbuclfle being; elongnrted` the hooks heing shiftable on their pivots sfo-that the)v a re adapted to be retracted under the head arms to expoee said seats the hooks beinepro vided with laterally projecting .studs hetween their piroted and swinejing` ends: and contra :tile springs connecting* the :studs ot each pa, ot hooks and oiiset by the studs trom the heads, so that the springs are shittable with the hoohs and are adapted to draw the hoolts inward against the rim flanges when the hooks are lwojected, and to drew the hooks inward under the hends when the hooks. are retractech and confine the retracted hooks in ont ot the way positions.
